Here is a funtion that I use.
A user can enter a date in any of the following ways:
01 01 03
01-01-03
1-1-03
01-1-2003
1-01/03
1/1 03 you get the idea...
This function will standardize the date and make sure it's valid. If invalid it returns
"ERROR"
function fixdate($data){
$aux[0]="";
$aux[1]="";
$aux[2]="";
$z=0;
for($i=0; $i<strlen($data); $i++) {
if(is_numeric($data[$i])) {
$aux[$z].=$data[$i];
}
else {
$z++;
}
}
if(strlen($aux[0])==1) {
$aux[0]= "0".$aux[0];
}
if(strlen($aux[1])==1) {
$aux[1]= "0".$aux[1];
}
if(strlen($aux[2])==2) {
$aux[2]= "20".$aux[2];
}
$mdate= $aux[0]."/".$aux[1]."/".$aux[2];
if(checkdate($aux[0], $aux[1], $aux[2])) {
Return $mdate;
}
else {
Return "ERROR";
}
}//function

what function can I use to validate
that he put in a valid date?
I want to use checkdate but that needs the date split up into day, month
year.
Anyone have an easy way of doing this?
Thanks,
